DESCRIPTION:Turbulence\, a phenomenon observed by physicists i
n natural and laboratory flows\, is thought to be
described by Navier-Stokes equations (NSE). Mathem
aticians are wondering whether NSE are well posed\
, namely whether they can develop a singularity in
finite time from regular initial conditions. Give
n that\, it is natural to investigate regularity p
roperties of turbulence.\nIn this talk\, I will re
view available tools to investigate statistical an
d deterministic regularity of turbulent flows\, so
me of which are directly inspired from regularity
tools developed by mathematicians for NSE. I will
also describe the results of application of such t
ools to numerical simulations of NSE or to state-o
f-the art experimental measurements and discuss th
eir link and potential implication regarding regul
arity properties of NSE.
